Ios Engineer Interview Questions

7,320 ios engineer interview questions shared by candidates

On the interview with CTO I expected to answer some behavioral question, but instead got asked that leetcode problem. The problem: Imagine a Domino game. Each domino piece has 2 sides with numbers from 0 to 6. Given an array of these pieces, write an algorithm that would connect all domino pieces (sort them basically in the order that is correct, and it can go both sides). 45 minutes total interview length.
